IMPROVEMENT IN MEAT-CHOPPERS.

Specification forming part of Letters Patent No. 154,791, datedSeptember 8,1874; application filed 7 July 3, 1874. V i

To all whom it may concern:

Be it known that I, JOHN A. FBENZEL, of Sauk City, in the county of Saukand State of Wisconsin, have invented a new and valuable Improvement inMeat-Choppers; and I do hereby declare that the following is a full,clear, and exact description of the construction and operation of thesame, reference being had to the annexed drawings, making a part of thisspecification, and to the letters and figures of reference markedthereon.

Figure 1 of the drawing is a representation of a front view of mymeat-chopper. Fig. 2 is a vertical sectional view, and Fig. 3 is a rearview, of the same. Figs. 4, 5, and 6 are detail views.

This invention has relation to machines for chopping meat, wherein anumber of reciprocating cutting-blades are employed in combi-' nationwith a rotating chopping-block. It consists mainly in the employment ofguiderods, in combination with cutters applied to rods, which areactuated by cranks, whereby I obtain a rocking as well as an upand-downmotion of the cutters, and thus produce drawing cuts on the meat, and atthe same time avoid jar and concussion. It also consists in a ringplatform for the chopping block, which is adjustably applied to posts,whereby the said block can be conveniently raised or depressed, ascircumstances require. It also consists in a horizontal cross-barcarrying the cutter-guides, and secured to the uprights of the frame bymeans of wedges and clamps, whereby the cutters are readily detachedfrom their guides when it is desired to adjust them or remove them to besharpened. It finally consists in adjustably securing the cutters tocross-heads on the lower ends of their rods, so that they can be set towork properly and readily removed for sharpening them, as will behereinafter explained.

In the annexed drawings, A designates an upright rectangular frame,which is supported upon a stand, 13; and O designates a horizontalcrank-shaft, which has its end bear ings in journal-boxes located nearthe upper end of frame A, and which is constructed with a circularplate, a, at the middle of its length, on the periphery of which disk afixed yoke, a, bears, and thus steadies the crankshaft and preventsvibration thereof. One end of shaft 0 carries a balance-wheel, and theother end a pinion spur-wheel, b, with which latter a large spur-wheel,b, engages. This wheel I) is keyed on a horizontal shaft, D, carrying ahand-crank, D, by which the machine is operated. In practice the wheelsb b will be hooded to prevent their teeth from being clogged with meat,&c. the cranks of shaft G has applied to it a rod,

E, which has secured rigidly to its lower end a T-shaped cross-head, 0,through one of the arms of which a guide-rod, d, passes freely, whichrod is rigidly secured at its upper end to a bracket,'e, on a horizontalcross-bar, F. The other two arms of cross-head 0 receive loosely throughthem two screws, ff, which are secured rigidly to the cutter g,and'which receive nuts 6 above and below said arms. The cutters g' arethus detachable from their cross-heads c, and they are also adjustableup or down thereon. The bar F, to the brackets of which the guide-rods dare secured, is applied to the grooved backs of the frame uprights bymeans of wedges j formed on its ends, which wedges are fitted into saiduprights and secured by means of clamps k and screws 1, on which latterhandled nuts I are applied. By loosening the nuts Z the bar F can bedetached from the frame A and the cutters g adjusted or removedconveniently. Gr

Each one of designates the chopping-block, which is of circular form,and constructed with a flange, h. This block G is removably appliedinside of the raised rim of a horizontal spur-wheel, H, and preventedfrom turning thereon by means of a stud, i. The center of the wheel Hhas its bearings in a socket, m, rising centrally from a platform, J.The outer'portion of Wheel H is supported on anti-friction wheels n,which are applied to the rim of the platform J. This platform J issupported on the base or stand B by means of four screws, 19, which passfreely through ears 0, and receive nuts 1) on them above and below theseears. The platform is thus adjustable, and the block G can be readilyraised and depressed. Wheel H engages with a spur-wheel, q, on avertical shaft, K, at the back of frame A, which shaft carries on itsupper end a spur-wheel, g, which engages with a worm-wheel, r, on thecrank shaft 0. The chopping-block G thus receives slow rotation when thecutters are at work. L designates a guard or shield, which is hung fromthe cross-bar F, for the purpose of preventing the escape of meat fromthe block G during the chopping operation. r i

What I claim as new, and desire to secure by Letters Patent, is-

1. Guide-rods d, in combination with cutters g, which are actuated by acrank-shaft,

0, through the medium of rods, substantially as described.

2. A circular platform for the choppingblock G and spur-wheel H incombination
